The following tables are updated every five years:

Age-specific fertility rates for the major ethnic groups

Fertility rates by single year of age for Māori, Pacific, Asian, and European populations, 2001, 2006, and 2013.

Regional fertility rates

Fertility rates by five-year age group for regional council areas, 1996, 2001, 2006, and 2013.

Following a review of regional fertility rates, Statistics NZ considers that quality data can only be produced for census years. Regional fertility rates will therefore no longer be published for other years.

The following tables remain available but will not be updated:

Median and average age of mother

Average age of mother, nuptial, ex-nuptial and total confinements, 1962–2009
